Finally, Gigabyte’s 3D1 is a great performer. Granted, it never doubles the performance of a single GeForce 6600 GT graphics card. It does come close in many situations though, especially at the high resolutions that gamers demand. In the worst cases, Gigabyte’s 3D1 will make one extra resolution playable with eye-candy enabled. So, if you had a 6600 GT that topped out at 1024x768 with 4xAA turned on, there’s a good chance that the 3D1 will handle 1280x1024 without a problem. In the very best cases, the 3D1 will approach, and even surpass, the performance of a single GeForce 6800 GT card.
